Indeed. However, I believe numscons has an advantage here, because most
(but not all) informations for fortran compilers are obtained at
runtime. Testing that compiling works is hard, but testing that the
runtime parser works is easy and testable on every platform. Since my
parser is modeled on autoconf AC_F77_LDFLAGS and co, it should work with
many compilers (except windows, obviously).

If you have a few minutes to spend, and access to compilers not cited in
my list, would you mind using some of the small tools I hacked to get
informations on fortran compilers ? For example, for g77:
- python ac_f77_ldflags.py g77
- python f77link_output.py g77
should give all the necessary informations to link g77 object code and
object code compiled by a C compiler. The tools are in
numscons/tests/fortran. The first one runs autoconf and get the value
from AC_F77_LDFLAGS for a given F77 compiler, whereas the other one just
compile an empty fortran program, to get the verbose output of the link
step. They should work on any platform (of course, the ac_f77_ldflags
won't work in a standard windows environment, since autoconf needs a
basic unix environment).
